Republicans from border states and the U.S. Chamber of Commerce are criticizing President Trump’s threat to close the border with Mexico over his belief that Mexico isn’t doing enough to stem the tide of migrants from Central America. USA Today reports that the administration could start shutting down ports of entry this week. Critics point out that Mexico was America’s third-largest trading partner last year and they’re concerned about the effect closing the border would have on the economy. The Philadelphia Inquirer says House Democrats are talking about holding a vote on the border closing later this month to force border state Republicans to take a stand on the administration’s controversial proposal. Politico says Trump plans to visit the border on Friday while GOP members try to guess which move the president will make.
